India tested two times. Both times we attracted trade and nuclear sanctions. Pokhran II test under NDA regime also prompted the US to constitute the NSG - curbing our right to nuclear trade. As a result for want of spares and fuel, our capacity utilization of reactors started declining.
If we test now, sanctions will hit India's growth story which has already taken some blows due to global inflation. Unlike previous times, the deal permits us to test if other countries test.
There is also an unofficial ban on nuclear testing. This is why no country has tested a nuclear device for decades.
